Carol Meyrowitz took over TJX, the largest off-price retailer (home to T.J.Maxx and Marshall's), just as a major security breach unraveled early last year. That violation, which
compromised the information of millions of customers, led to an investigation and millions of dollars of settlement fees paid by TJX to Visa and MasterCard.

But not everything has been burdensome for the 25-year retail vet: Meyrowitz recently reported the company's financial results, including a 4.6% net income increase and a 22% dividend
hike for shareholders.
